Întrebări frecvente
What should I NOT plant near Fennel?
Avoid Coriandrum sativum, Common Grape Vine, Tomato, and 48 other antagonists. Reasons vary — allelopathy, shared pests, or resource competition. See the section above for each plant's specific issue.
Is companion planting scientifically proven?
Some mechanisms are well-documented (legume nitrogen fixation, allelopathy in walnut and fennel, nematode suppression by marigolds). Others are traditional pairings with anecdotal support. We cite both, but mark mechanism strength where available.
